Display method of information indicating an operating status of a manufacturing system

Abstract

A display method includes: displaying, in a first screen area, a line segment indicating a passage of time from start to end of a manufacturing process in each of process, with time axes being aligned in a same direction between the processes, in a state being segmented for each process in order of execution of the process, for each of one or more products manufactured by a manufacturing system; and displaying, in a second screen area, a graph indicating a passage of time from start to end of a manufacturing process, with time axes being aligned in a same direction as time axes in the first screen area, based on information of a start time and an end time of a manufacturing process in one or more manufacturing facilities included in a selected first process among the processes, for each of the manufacturing facilities in the first process.

What is claimed is: 
     
       1. A display method of information indicating an operating status of a manufacturing system that includes a plurality of processes to be performed sequentially to manufacture one product and includes one or more manufacturing facilities that perform a manufacturing process in each of the processes, the display method comprising:
 displaying, in a first screen area, a line segment indicating a passage of time from start to end of a manufacturing process in each of the processes, with time axes being aligned in a same direction between the processes, based on information of a start time and an end time of a manufacturing process for one product in each of the processes, in a state being segmented for each process in order of execution of the process, for each of one or more products manufactured by the manufacturing system, by a processor; and 
 displaying, in a second screen area, a graph indicating a passage of time from start to end of a manufacturing process, with time axes being aligned in a same direction as time axes in the first screen area, based on information of a start time and an end time of a manufacturing process in one or more manufacturing facilities included in a selected first process among the processes, for each of the manufacturing facilities in the first process, by the processor. 
 
     
     
       2. The display method according to  claim 1 , wherein
 the first screen area and the second screen area are displayed side-by-side; 
 specification of time in the first screen area or the second screen area is received; and 
 a line segment spanning over the first screen area and the second screen area corresponding to the received time is displayed. 
 
     
     
       3. A display method of information indicating an operating status of a manufacturing system, in the manufacturing system in which a manufacturing process for manufacturing one product includes one or more manufacturing facilities that perform a manufacturing process, the display method comprising:
 generating, by a processor, first display information including information indicating a passage of time for each passage of time from start to end of a manufacturing process and information indicating a load on the manufacturing process in the passage of time, for each of the manufacturing facilities, based on information of a start time and an end time of a manufacturing process in one or more manufacturing facilities included in the manufacturing process, and 
 displaying, by the processor, the first display information. 
 
     
     
       4. The display method according to  claim 3 , wherein
 the manufacturing process includes a plurality of processes to be performed sequentially to manufacture the one product, and 
 the generating includes receiving selection with respect to any process among the plurality of processes, and includes generating the first display information related to a first process for which the selection has been received. 
 
     
     
       5. The display method according to  claim 3 , wherein information indicating the load indicates a degree of actual throughput with respect to maximum throughput that can be treated by one manufacturing process. 
     
     
       6. A display method of information indicating an operating status of a manufacturing system, in the manufacturing system that includes a plurality of processes to be performed sequentially to manufacture one product and includes one or more manufacturing facilities that perform a manufacturing process in each of the processes, the display method comprising:
 displaying, in a first screen area, a line segment indicating a passage of time from start to end of a manufacturing process in each of the processes, with time axes being aligned in a same direction between the respective processes, based on information of a start time and an end time of a manufacturing process for one product in each of the processes, in a state being segmented for each process in order of execution of the process, for each of one or more products manufactured by the manufacturing system, by a processor; 
 receiving, by the processor, selection of any line segment among line segments displayed in the first screen area; and 
 displaying, by the processor, a graph corresponding to a first manufacturing facility identified by a first line segment for which selection has been received in a state of being able to be distinguished from graphs corresponding to other manufacturing facilities, in a second screen area in which a graph indicating a passage of time from start to end of a manufacturing process is displayed in a state with time axes being aligned in a same direction as the time axes in the first screen area, based on information of a start time and an end time of a manufacturing process in one or more manufacturing facilities included in a first process that is identified by the first line segment for which selection has been received, for each of the manufacturing facilities in the first process. 
 
     
     
       7. The display method according to  claim 6 , wherein the graph is a line segment connecting a point corresponding to a start time of a manufacturing process and a point corresponding to an end time thereof. 
     
     
       8. A display method of information indicating an operating status of a manufacturing system, in the manufacturing system that includes a plurality of processes to be performed sequentially to manufacture one product and includes one or more manufacturing facilities that perform a manufacturing process in each of the processes, the displaying method comprising:
 displaying, in a first screen area, a line segment indicating a passage of time from start to end of a manufacturing process in each of the processes, with time axes being aligned in a same direction between the respective processes, based on information of a start time and an end time of a manufacturing process for one product in each of the processes, in a state being segmented for each process in order of execution of the process, for each of one or more products manufactured by the manufacturing system, by a processor; 
 receiving, by the processor, selection of an area corresponding to any process in the first screen area; and 
 displaying, in a second screen area, a graph indicating a passage of time from start to end of a manufacturing process, with time axes being aligned in a same direction as time axes in the first screen area, based on information of a start time and an end time of a manufacturing process in one or more manufacturing facilities included in a first process that is identified by a selected area, for each of the manufacturing facilities in the first process, by the processor.
